Summary: @neon/sdk is the official TypeScript SDK for the Neon API, a modern, fetch-based replacement for @neondatabase/api-client. It exposes every platform resource through ergonomic namespaces on a single client (neon.projects, neon.branches, neon.postgres, neon.storage, neon.functions, neon.snapshots, neon.auth, and more), with one result contract, typed errors, automatic retries, readiness polling, and auto-pagination built in. A raw 1:1 layer exposes every endpoint and is generated from the Neon OpenAPI spec.

• OpenAPI spec

@neon/sdk wraps the entire Neon API in one typed, fetch-based client. You authenticate once, then reach every resource through a namespace on neon.*: projects, branches, the Postgres data plane, object storage, functions, and Managed Better Auth. Retries, readiness polling, auto-pagination, and typed errors are built in.

It replaces @neondatabase/api-client, the deprecated Axios-based SDK. New projects should use @neon/sdk. See the migration guide for method mapping and error-handling changes.

Building for agents?:

@neon/tools wraps this same client and publishes selected methods as typed agent tools, with adapters for MCP, Mastra, and Eve. Use it when a model drives the operations; use @neon/sdk when your own code does.

Note: Not every endpoint has an ergonomic wrapper

createNeonClient namespaces cover common workflows (projects, branches, Postgres resources, snapshots, and more). They do not wrap every Platform API operation. For endpoints without a namespace method, use the raw layer below or the Neon API Reference.

npm install @neon/sdk

import { createNeonClient } from "@neon/sdk";

const neon = createNeonClient({ apiKey: process.env.NEON_API_KEY! });

const { data, error } = await neon.projects.list().all();
if (error) throw error; // typed NeonError
data; // ProjectListItem[]

Every method follows this shape: select a namespace, call a method, and receive a { data, error } result. The reference below documents each namespace and method against that single contract.

Each method takes a single named-parameter object: the path selectors (projectId, branchId, and any resource id such as roleName or slug) and any input or query fields are merged into one flat object, followed by an optional trailing options argument ({ throwOnError?, waitForReadiness?, signal? }, omitted from the tables for brevity).

Important: Named parameters in v5 and later

@neon/sdk v5 replaced positional arguments with a single named-parameter object, and v6 is the current major. For example, neon.branches.get(projectId, branchId) is now neon.branches.get({ projectId, branchId }). If you're upgrading from v4, update your calls to the object form shown throughout this page. See Upgrading from v4.

In the reference tables, the Returns column names the resolved resource, the type of data on success (or the value returned directly when throwOnError is set). A method resolving to void has no resource body; Paginated<T> is the lazy, auto-paginated list described below.

Nearly every method needs a projectId, and branch-scoped methods also need a branchId. Get these from neon.projects.list() and neon.branches.list({ projectId }) (or neon.branches.getDefault({ projectId }) for the default branch), reading .id off each result.

createNeonClient(config) accepts:

const neon = createNeonClient({
  apiKey: process.env.NEON_API_KEY!,
  orgId: "org-cool-forest-12345678",
  throwOnError: true,
});

Four behaviors are shared by every method: the result envelope, typed errors, pagination, and async workflows.

By default, no try/catch. Each call resolves to a discriminated { data, error } envelope; check error, then data is narrowed:

const { data, error } = await neon.projects.get({ projectId: "late-frost-12345" });
if (error) return; // error: typed NeonError union
data; // narrowed to Project

To throw instead, set throwOnError on the client (or per call). The return type narrows to the bare resource:

const neon = createNeonClient({ apiKey, throwOnError: true });
const project = await neon.projects.get({ projectId: "my-project" }); // Project (throws on error)
const { data } = await neon.projects.get({ projectId: "my-project" }, { throwOnError: false }); // opt out per call

The error channel, and what throwOnError throws, is one hierarchy of Error subclasses, discriminated on kind:

const { error } = await neon.branches.get({ projectId, branchId: "nope" });
if (error?.kind === "not_found") {
  // handle the 404
}

Methods labeled Paginated return a Paginated<T>; the cursor is managed for you:

const { data: all } = await neon.projects.list().all(); // every page
const { data: one } = await neon.projects.list().page(); // just the first page
for await (const project of neon.projects.list()) {
  // stream item by item
}

Neon mutations return operations that complete in the background. The client-wide waitForReadiness default is false. projects.create, branches.create, and both createAndConnect workflows turn polling on for that call.

create returns the resource. createAndConnect also waits, then returns { branch, endpoint, connectionString } (or { project, connectionString }). The primitive underneath is neon.operations.waitFor({ operations }).

Pick one. create uses REST field names (parent_id). createAndConnect uses { name?, parentId?, compute? }. Both fold into the same params object alongside projectId.

const { data: branch, error } = await neon.branches.create({
  projectId,
  name: "preview",
});
if (error) throw error;

const { data, error: connectError } = await neon.branches.createAndConnect({
  projectId,
  name: "preview-uri",
});
if (connectError) throw connectError;
const { connectionString } = data;

On any other namespaced mutation, pass { waitForReadiness: true } as the trailing options argument to poll before the call resolves. For raw API calls that return an operations array, use neon.operations.waitFor instead.

The client groups the API into resource namespaces. Projects and branches are the core surfaces: projects create, manage, and share projects, and branches branch a project's data and schema. The Postgres data plane lives under postgres: compute endpoints, roles, databases, the Data API, and connection strings.

Branch-scoped platform services include storage (S3-compatible object storage), functions, credentials, aiGateway, and auth (Managed Better Auth, OAuth providers, and users). For data lifecycle and async work, use snapshots for point-in-time snapshots and restore, and operations to poll asynchronous operations.

Account-level surfaces round out the client: consumption for billing metrics, apiKeys, and regions / user.

Create, manage, and share Neon projects. One API call per method; list is paginated. REST: Projects API

// Provision a project, poll until ready, return a pooled connection string
const { data } = await neon.projects.createAndConnect({
  name: "tenant-42",
  region_id: "aws-us-east-1",
  pooled: true,
});
// data: { project, connectionString }

Share a project with additional users by email.

Branch a project's data and schema. create attaches a read-write endpoint by default. REST: Branches API

Three modes: default compute, schema-only (noCompute: true), and create-plus-URI.

const { data: prod } = await neon.branches.getDefault({ projectId });

await neon.branches.create({
  projectId,
  name: "preview/pr-123",
  parent_id: prod?.id,
});

await neon.branches.create({
  projectId,
  name: "schema-only",
  parent_id: prod?.id,
  noCompute: true,
});

const { data, error } = await neon.branches.createAndConnect({
  projectId,
  name: "preview/pr-123-uri",
  parentId: prod?.id,
  compute: { minCu: 0.25, maxCu: 2 },
});
if (error) throw error;
const { connectionString } = data;

The Postgres data plane of a branch: compute endpoints, roles, databases, the Data API, and a connection-string helper. REST: Endpoints, Branches, Data API

const { data: uri } = await neon.postgres.connectionString({ projectId });

Compute endpoints, scoped to a project.

Postgres roles, scoped to a branch.

// Reveal a role's password, or rotate it
const { data: password } = await neon.postgres.roles.password({ projectId, branchId, roleName: "neondb_owner" });
const { data: role } = await neon.postgres.roles.resetPassword({ projectId, branchId, roleName: "neondb_owner" });
// role.password holds the new secret

Databases, scoped to a branch.

The Neon Data API, scoped to a branch and database.

Branch-scoped, S3-compatible object storage. get returns whether storage is enabled and the branch's S3 endpoint metadata; buckets and objects are nested underneath. REST: Storage, Buckets

// Upload via a presigned PUT
const { data: presign } = await neon.storage.objects.presign({
  projectId,
  branchId,
  bucketName: "avatars",
  objectKey: "user-1.png",
  operation: "upload",
  content_type: "image/png",
});
if (!presign) throw new Error("presign failed");

await fetch(presign.url, {
  method: "PUT",
  headers: { ...presign.headers, "Content-Length": String(bytes.length) },
  body: bytes,
});

Branch-scoped Neon Functions. REST: Functions API

// Deploy a bundled index.mjs inside a zip (first deploy must include the zip)
const zip = await Bun.file("bundle.zip").arrayBuffer();
const { data: deployment } = await neon.functions.deploy({
  projectId,
  branchId,
  slug: "api",
  zip: new File([zip], "bundle.zip", { type: "application/zip" }),
  runtime: "nodejs24",
});
// Poll neon.functions.get until current_deployment.status is "completed"

Branch-scoped credentials with explicit scopes. Secrets (api_token, s3_secret_access_key) are returned once, on create. REST: Credentials API

Branch-scoped AI Gateway endpoint metadata. REST: AI Gateway API

Point-in-time snapshots, restore, and backup schedules. REST: Snapshots API

restore behaves differently depending on the target:

• As a new branch (no targetBranchId), it finalizes by default and is ready to use immediately.
• Onto an existing branch, it does not finalize by default, so you can preview first.
• Transaction-style with preview: it restores un-finalized, runs your callback against the restored branch, then commits if the callback returns true or aborts (deletes the preview branch) if false, unless keepOnAbort is set:

await neon.snapshots.restore({
  projectId,
  snapshotId,
  targetBranchId,
  preview: async (branch) => (await checks(branch)) === "ok", // true commits, false aborts
});

Read operations and wait for them to finish. REST: Operations API

// Wait on operations from a raw call (or when readiness polling is off)
const { data } = await raw.createProjectBranch({
  client: neon.client,
  path: { project_id: projectId },
  body: { branch: { name: "wip" } },
});
const { error } = await neon.operations.waitFor({ operations: data!.operations }, { timeoutMs: 120_000 });

Branch-scoped Managed Better Auth. The legacy project-scoped endpoints are deprecated and remain raw-only. REST: Authentication API

OAuth providers (Google, GitHub, and others).

The redirect-URI whitelist.

Cursor-paginated billing metrics. Each method takes { from, to, granularity, org_id, project_ids? }, where from/to are ISO timestamps, granularity is "hourly" | "daily" | "monthly", and org_id names the org to report on; perBranchV2 also requires project_ids. org_id defaults to the client orgId when set. Consumption requires a Scale plan or above. REST: Consumption API

// Stream every project's daily usage across a range
for await (const project of neon.consumption.perProject({
  from: "2026-06-01T00:00:00Z",
  to: "2026-06-30T00:00:00Z",
  granularity: "daily",
  org_id: "org-...", // the org to report on; consumption requires a Scale plan or above
})) {
  console.log(project);
}

Manage account-level API keys. REST: API Keys API

Active regions and the current account. REST: Regions, Users

@neon/sdk v5 introduced one breaking change that runs through every namespace: resource methods take a single named-parameter object instead of positional arguments. Path selectors and input fields are merged into one flat object, followed by the same optional call-options argument.

// v4 (positional)
await neon.branches.get(projectId, branchId);
await neon.postgres.roles.password(projectId, branchId, "neondb_owner");
await neon.storage.objects.presign(projectId, branchId, "avatars", "user-1.png", {
  operation: "upload",
});

// v5 and later (named parameters)
await neon.branches.get({ projectId, branchId });
await neon.postgres.roles.password({ projectId, branchId, roleName: "neondb_owner" });
await neon.storage.objects.presign({
  projectId,
  branchId,
  bucketName: "avatars",
  objectKey: "user-1.png",
  operation: "upload",
});

The { pooled } option on projects.createAndConnect and branches.createAndConnect, and the operations argument to operations.waitFor, also move into the params object. postgres.connectionString and the consumption.* methods were already object-shaped and are unchanged.

v6 is the current major. It extends the triggers surface (storage_object_created alongside schedule) and does not change the named-parameter shape introduced in v5.

Anything not wrapped above is available as a raw, 1:1 function. Pass neon.client to reuse the client's auth and base URL:

import { raw } from "@neon/sdk";
// or, for guaranteed tree-shaking: import { getProjectBranchSchema } from "@neon/sdk/raw";

const { data, error } = await raw.getProjectBranchSchema({
  client: neon.client,
  path: { project_id, branch_id },
  query: { db_name: "neondb" }, // db_name is required
});

The raw layer speaks the same result contract as the ergonomic client: { data, error } by default, or the bare resource (throwing the typed NeonError) with throwOnError: true. There is no responseStyle switch. Every request, response, and error type is re-exported flat from @neon/sdk for import type { Project, Branch } and the rest.

The raw layer and all request, response, and error types are generated from the Neon OpenAPI spec using @hey-api/openapi-ts. The ergonomic namespaces documented above are hand-written on top of that generated layer. When the API adds an endpoint, it appears in the raw layer automatically; the namespace wrappers are added deliberately. The source lives in neondatabase/neon-pkgs.
